IMPROVEMENT IN HARVESTERS.

S pecilication forming part of Letters Patent No. QGJQS, dated November 22, 1859.

To all whom t may concern:

Be it known that I, WILLIAM MORRISON, of Carlisle, in the county ofOumberland and State ot Pennsylvania, have invented certain new and useful Improvements in Harvesters; and I do hereby declare that the followingisafull and eXact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure lis aperspec'tive view of my im proved cutting apparatus. Fig. 2 is a top view of one ofthe lingers detached. Fig. Sis a bottom View of the same; and Fig. 4c is a longitudinal section through one ot' the lingers, showing the manner of attaching the same to the linger-bar.

To enable others skilled in the art to make and use my invention, I will proceed to dcscribe it.

The same letters ofret'erence, wherever they occur in the several gures, rel'er to the saine parts.

In the said drawings, A represents the tinger-bar of a cutting apparatus; B, the lingers; O, the cutter-bar, and D the cutters connected therewith. E are the stationary cutters,which are secured to the fingers in the manner hereinafter described. G are the fenders. a c are the bolts, and b b the nuts for securing the ngers to-the nger-bar. ff are the caps or guards to the lingers, which are open at their rear end, and are forked in the manner shown in the drawings.

The lingers B are slotted or forked, and are open at their rear ends in the manner shown in the drawings, and are formed with the rabhets or ledges d, against which the heads c of the bolts a bear for thepurpose of securing the fingers to the linger-bar. It will be seen that by this construction of the fingers, by merely loosening the nuts b on the bolts ce, and with out removing them from the bolts, the lingers may be readily withdrawn or removed and replaced by new ones, in the event of being injured or brokenLwithout the necessity of removing the bolts or the nuts thereon from the t linger-bar.

The stationary cutters E are forked at the forward end and lit in a corresponding angularly-formed slot in the forward part ofthe linger, as shown hy the dotted lines in Fig. 2. This formation serves to secure the forward end ofthe stationary cutter in the proper position for the performance of its work. Said stationary cutter is further secured froth lateral play by fitting between the raised part of the fenders G, which are so formed that when the cutters areV in place on the lingers the surface of the fenders shall liush with the surface of the stationary cutter. This stationary cutter thus steadied in its place upon the finger 1s hound down thereto by having the heel thereof slipped under-the finger-har as the linger-is slipped into place on the bolts,`and the tightening of the bolts lirmly secures the said cutters to the face of the fingers. It will be seen that by this construction, by merely loosening the nuts on bolts a, the linger may be slipped forward slightly and the cutters E readily removed and sharpened and replaced, and again secured, as before, with very little labor and without the necessity ot' removing the lingers or the bolts which secure the same to the lingers, thereby effecting a great saving of time, and without any danger' of the bolts and nuts becoming lost. The construction ot' the reciprocating cutter-bar and cutters, being the same as those in common use, does notneed further description here.

Having thus fully described my invention, what I claim as new, and desi Letters Patent, is-

Providing the rear endofthe finger with the open slot d, whereby I am enabled to readily remove the stationary cutters and lingers and to replace them without detaching the bolts or nuts which secure the lingers to the finger-bar, in the manner and for the purpose specified.

WM. MORRISON.
